Outer retinal tubulations response to anti-VEGF treatment.

ORTs documented by SD-OCT may exhibit multiple types of longitudinal changes, such as collapse, recurrence or enlargement, which could be associated with anti-VEGF treatment or spontaneous. Some ORTs may have a vascular component or may be vascular in nature, considering their response to anti-VEGF treatment, while other ORTs are likely composed only of degenerating photoreceptor cells and may collapse independently from anti-VEGF treatments.
